Surgical Resection for Solitary Myocardial Metastasis of Gastric Cancer.

Abstract

Six years after primary surgical treatment for gastric cancer, fluoro-deoxy-glucose positron emission tomography/computed tomography was performed in a 72-year-old man, and demonstrated an increased fluoro-deoxy-glucose uptake in the apex of the left ventricle. Magnetic resonance imaging also revealed a solitary small myocardial tumor. Under cardiopulmonary bypass, tumorectomy was performed with a macroscopically sufficient margin. Histopathologic examination showed adenocarcinoma with poor differentiation developed in the myocardium and pericardial fat; these findings were compatible with the previously resected gastric cancer. The postoperative course was uneventful; the patient has been alive for 29 months without any evidence of local recurrence or cardiac events.
